What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study examined the effects of a vocal hygiene education program delivered via videoconference on voice quality and self-perceived vocal outcomes among Muslim religious officials in Turkiye. The participants were 26 imams, aged between 28 and 51 years. All participants completed a seven-week study procedure, consisting of two structured videoconference-based vocal hygiene sessions and a four-week vocal hygiene implementation period. Voice-Related Quality of Life (V-RQOL), Voice Handicap Index-10 (VHI-10), Acoustic Voice Quality Index Version 2.06 (AVQIv2), jitter, shimmer, and harmonics-to-noise ratio (HNR) were assessed before and after the program. V-RQOL scores increased from 82.60 ± 19.91 to 89.23 ± 11.61 (p = 0.006). VHI-10 scores declined from 9.58 ± 5.24 to 5.96 ± 4.43 (p < 0.001), and AVQIv2 scores decreased from 3.12 ± 0.85 to 2.35 ± 0.61 (p < 0.001). Jitter, shimmer, and HNR values showed improvement but did not reach statistical significance. These findings suggest that vocal hygiene education delivered via videoconference was associated with favorable changes in self-reported outcomes and AVQIv2 scores, among Muslim religious officials.
